These are my downstairs neighbours. They've been gone for at least a week, there is post sticking out of their letterbox and no-one has gone in or out. Every day when it gets dark I hear the dog whining, and it's making me sad, and at this point I assume the dog is not long for this world, as no-one can have been giving it food or water.
I can't see in through the windows as they all have closed curtains or blinds or sheets stuck over them. The neighbours are generally very loud and when the dog barks while they're there, they scream "shut up" at the top of their lungs at it. When their friends come round they don't knock, they stand outside and scream, so I know that people have come looking for them and they aren't in.
I looked at the RSPCA website, but it only covers finding a dog or making a noise complaint about a barking dog, nothing for a dog being left to die within residential premises.
So do I call someone, and if so who?, or do I just assume everything is somehow fine?
